`Specificatiers Patent. Y Patented July" 2li, 1916.

Application filed. January 18, 1911. Serial No. 603,372.

To all whom z't may concern.:

Be it known that I, CHARLES S. LABoFisH, a citizen of the United States, residing at Washington, in the Districtk of Columbia, have invented certain new and useful lmprovenients in Brush-Machines, of which the following is a specification.

The yinvention herein enunciated relates to improvements in brush making machines and comprises certain new and useful 1mprovements on themachines shown and described in my applications dated Dec. 18, 1905; Sept. 3, 190 and Oct. 8,1909, bearing Serial Nos. 292,318; 391,068; and 521,725 respectively. i

The objects ofthe present improvements are: first, to provide the cells 'in hard-substance brush blanks with means for engagement with eXpansible knot fasteners;

second, to provide means for'gathering a row of separated tufts of filaments and 1nterposing the same between tuft-doublingand-inserting devices; third, to provide means for simultaneously feeding knot fasteners to a plurality of tuft-doubling-andinserting devices; fourth, to provide 4for splaying the, knots in the brush without rocking the brush blank; fifth, to provide means for automatically controlling the m0- tion-reversing means of one or more drivingmechanisms so as to enable the machine to carry on successive operations without the aid of the operator; and, sixth, to provide for feedingknot fasteners to a plurality of rows of tuft inserters from a single source. I attain these objects by the mechanisms, means, and devices illustrated in the accompanying drawings, in which- Figure l -is an enlarged view of parts containing a longitudinal-half of a single-tauft doubling-and-inserting mechanism.

Some of the new and useful features of :invention herein shown and described are said features are shown and described as aplied to multi-serial brush making machines, l) wish to have it clearly understood, shall not operate to limit them thereto.

The approved substance of which tooth brush handles are made is bone. The texture of bone is so dense and hard that it is impossible to force the limbs of expansible sheet-material knot fasteners, such as shown in the patent to Gane No. 378,130, into the walls of the cells in bone brush blanks. Hence, the use of expansible sheet-material knot fasteners is, to my knowledge, at the present limited to impressible-substance brush blanks, such as wood or Celluloid.

To enable the brush maker to use expansible sheet-material knot fasteners in bone brush blanks, each of the cells b in the bone brush blank a is provided with means for engagement, preferably oppositely disposed cavities c for the corners of the limbs d of the expansible sheet-material knot fastener e to engage in the manner shown in Fig. 2. The cavities c can be readily made by merely drilling a longitudinal hole f so as to perforate the partitions g between the cells in the row, as shown in Fig. 1.

Expansible sheet-material knot fasteners constructed in the manner shown in the patent to Gane mentioned, and herein marked e in Fig. 1, are, however, open to very serious objections. Owing to the kerf .in said fastener and the necessarily pointed end p of the plunger bearing against the inner corners of the yielding limbs l when driving the bight of the knot with the plain end cl of the fastener into the cell in the brush blank, it is extremely difficult, if not impossible, to force the bight of an ample knot into the cell; as the excessive pressure exerted on the yielding limbs d would spread them and in some constructions of knot-conveying means wedge them in the nozzle, and

, thus create excessive friction, and in others spread the limbs of the fastener to such an extent as to prevent its entrance into the cell.

To enable the brush maker to force the bights of ample knots into cells in hardsubstance brush blanks and anchor lthe knots in the cells by means of expansible sheetmaterial knot fasteners, I construct the knot fastener as shown in Fig. 4;.

.The edge of the end D ofthe knot fastener E is plain, that of the opposite end, and the edges of the sides in proximity thereto, are cut out so as to form short, rounded limbs D relieved at L sothat when the fastener is forced against a hard surface or the bottom of the cell B in hard-substance brush blanks said limbs Will tend to curl laterally outward and thus spread out and enter the oppositely disposed cavities C therein, as shown in Fig. 5. The end D being plain, the forcing .of the amplestknot with this fastener can in nowise expand it at any point in its travel to the cell, nor at any inappropriate point in the cell until the limbs D strike the bottom of the cell.

My tuft-doubling-and-inserting mechanism, constructed for anchoring the knots in the cells by means of individual knot fasteners, isprovided with suitable means for holding the brush blank A, having the cell B therein, in contact'with a member containing a tuft-conveying opening, or conduit,

and a knot-fastener-conveying channel. The said conduit and channel are so constructed that their imaginary lines crossing at one of the orifices of said conduit will register with the diameter of the said cell, to the end that the bight of the knot and the width of the fastener be of thel precise diameter o'f the cell, instead of somewhat smaller as heretofore, and thus enable the insertion of an ample knot and a close fitting fastener.

To facilitate the forming of said conduit and channel, the said, member is composed of conjoined parts 175 and 16. The conduit 17 is made broad at the orifice opposite said cell and courses tapering widthwise to the cell B, in order that an ample tuftof filaments be readily doubled and easily conducted to the cell B and the bight of the knot tightly compressed at the point of transition from the conduit into the cell to the diameter of the cell and entered thereinto without cutting or abrading of the filaments against the sharp edges of the orice of the cell in hard-substance brush` blanks, or split a bone brush handle along the row of cells. y

Grooves 1.8, disposed opposite each other, are made in the parallel walls of said conduit,vand, to the end hereinbefore specified said conduit and grooves are of such dimensions as that the distance between vthe opposite walls of the conduit at its smaller orifice and the distance between the opposite walls of the grooves 18 register with the diameter of the cell, asiclearly shown in Figs. 3 and 4 and indicated by the dotted circle in Fig. 6. Opposite said knot-conveying, o r conduit-containing, member is a plungerand-knot-fa-stener-guiding member, preferably similarly composed of conjoined parts 19, 20, having an elongated opening 9.1- F ig. 7-of the width and height of the oppositely disposed grooves 18 and held so that said opening 21 registers with said grooves 18, as clearly vshown in Figs. 3 and 4f. Interposed between said two members, and in close contact with the plunger-and-knot-fastener-guiding member, is .a movable tuft holder, which to facilitate the manufacture thereof is composed of conjoined bars 22, 23,

preferably provided with a rib 26 along the line of `juncture of said bars for the purpose hereinafter specified and having an opening 24 and oppositely disposed grooves 25, therein `which when in the position shown lll@ scribed. In the space .between the space 26 'the continuity of the in Figs. 3 and 4 extend between, the grooves 18 and opening 21, and a space 26 forming notches in the edges of said rim alongA the space between In said opening 21 is guided a plunger 27 and a suitable knot-fastener, thereinto through the opening in the part 20 preferably by the means hereinafterv de- 26. of said tuft holder is held a tuft of filaments F. By this means the tuft F of requisite thickness is boxed in and the face of the member composed of parts 19 and 20, and overlies the opening 24 without interrupting composite knot-fastener conveying channel 21, 25, 18, as shown in Figs. 34 and 4. Upon forcingthe plunger 27 against the knot fastener E, the latter doubles the tuft F and forces its bight into the cell B in the brush blank A. Upon exerting further pressure on the fastener E, the outwardly-rounded ends D spread out and enter the previously made cavities C, in the-hard substance blank B, as shown in Fig. 5.

In certain kinds of brushes the blanks are too soft for expansible sheet-metal knot fasteners and too thin for staples. In such brushes I prefer to use the expansible knot .fastener E shown in Fig. 9. This fastener is made of suitable wire in the shape of `a short staple with the limbs D curved outwardly so as to favor partial straightening out of the loop vupon being forced against the bottom of the cell and thus ,project the limbs D into the wall ofthe cell in the .manner shown in Fig. 10.

In all the brush machinesthus far pattented I have knowledge of, the conduit, usually termed nozzle, is somewhat smaller than the cell in order to be .able to center it therein. As clearly shown in Figs. 3, 4, and 6, the major axis of the smaller orifice of the conduit- 17 and the distance between the opposite walls of the grooves 18 correspond with the diameter of the cell B, While the adit orifice of said conduit land. the opening 24 'in the tuft carrier are broad. By'means of this construction the tuft F is easily doubled and conducted to the point of transition from the conduit into the cell with very little friction, and at the point of transition the bight of .the doubled tuft is compresse to the diameter. of the cell. In virtue of the construction the forced into the cell without great friction against the sharp edges of its orifice, which in hard-substance brush blanks tends to cut or abrade the filaments, and in tufting a row of cells at a time in a tends to split the blank along the row of cells; and the ltuft rfastener may be made of the precise diameter of the cell and so as to enter tightly thereinto. v

Fig. 4A shows a modification, suited for row-tufting mechanisms, byl means of bone brush blank'- tuft is y which thev knot-fastener-conveying-channel described may be dispensed with. The row of conduits 5 is bisected by a fine slot 6-Fig. 4B-and the knot fasteners 7 `are connected by fine Shanks 8. Interposed bed .tween the brush blank 1 and the member composed of parts 5', 5 containing the row of conduits 5`is a plate 3 having holes 4 therein each of which forms a continuation .of one of said conduits and registers with one of the cells 2 in the blank 1. The partitions between the holes 4 in. the plate 8, at the point of contact with the member containing the conduits 5, are reduced to knife edges 4-Figs. 4A and 4C. In a slot 11, in the guide member 13, Vis guided a toothed bIa`de12 into a corresponding slot 14 in the movable tuft carrier 14 and into said slot 6. Upon moving the blade 12 into said slots in the tuft carrierand conduits, the connected row of knot fasteners 7 double the row of tufts in thetuft carrier 5 shove them into the holes 4 in the plate 3. Upon exerting further ypressure on the connected row of fasteners 7, the knife edges 4 sever the several shanks of the blade force the thus separated fasteners into .the cells, anchoring the knots in the manner shown in Fig. short stubs 8 tightly pressed against the walls of the cells by the purposely chamfered off teeth 12. To guard against the possibility of filaments entering the spaces between the connected fasteners 7, the con' the knots in any kind of brushes may lbe similarly connected in a row Vand separated.

at the cells in the brush blank by any means deemed appropriate. M

` In Figs. 11, 12, and 13 I have illustrated the further improvements of the presentinvention embodied in a multi-serial multiplebrush machine which by preference is constructed on the lines ofl the machines shown and described in the applications previously mentioned. In constructing this machine, a table 30, preferably circular in its contour, is suitably mounted upon legs 31. extending radially toward, and close to, the center of the table so as to support the weight thereon and also to serve as-guide members for a vertically-movable disk described hereinafter. `In the center of said held rotatably an annular brush-blank-carrier 35, preferably mounted upon anti-friction ,rollers 36, carrying a plurality of brush-blanks 37, arranged circularly therein, each of which is suitably stayed vertically, preferably by ribs 38, and suitably heldin close contact with the wall of the annular 14 and 8 and the teeth 12 4D, with the table, preferably in a recess 32 therein, 1s

Said tuft gatherer, to facilitate knob 43 in one 'direction the several shoes its manufacture, is composed of two bars 68, ao 39 simultaneously expand and press on the 6 8 and has a plurality of teeth 69 raised backs ofthe blanks 37, and by turning the upon the bars at their juncture and'openings rod 43 in the opposite direction the several or conduits 70 in the spaces between said ends 42 of the shoes are simultaneously teeth corresponding in number to, and regisdrawn toward the rod 43 and the brushes tering in spacing with, the conduits 50. 85 37 thereby released, as clearly shown, and Said openings 7() being, in the present illusindicated by dotted lines,'in Fig. 11. tration, similarly bisected by a slot 71 co- In the blank carrier 35 are rows of suitable incident with the slot 51 bisecting said contuft-conveying channels, or conduits, 50 corduits and the slot 61 in the block 60, for the responding in number to the cells 52 in the purpose of admitting a blade tuft inserter, 9o brush blanks 37 and arranged so that each when 011e is used, as clearly shown in Figs. conduit leads to a cell in a brush blank. 12and 13.

. knots, may be knots in the cells by longitudinally and transversely o `To hold the tufts in the row clenched against slipping laterally and to prevent filaments from entering the-space between the surfaces of the teeth 69 and the face of the block 60, which becomes of consequence when toothed blades are used in place of individual plungers, the tuft gatherer 68 is held movably in close contact with the block 60.. `And to be able to form the uninterrup ed, composite, knot-fastener-conveying chan: nel to be presently described, said tuft gatherer is held in close proximity to the plates 49 as well as to the block 60 opposite thereto, as shown in Figs. 12 and 13.

The bights of the double tufts, or the anchored, or fastened, in the brush blank by any means To be ablev to anchor the means of individualr fasteners, grooves 81 are formed in the blocks 60, corresponding grooves 82 inthe 'openings 70, and corresponding grooves.83 in the conduits 50. Said grooves register with one another and 'their orifices abut one another so as to form a' series of uninterrupt-- ed guide channels for each4 fastener 80 to travel from its initial lpoint to the cell in the brush blank, unimpeded byY any nicks or openings inl the path as clearlymsho-wn in Figs.f12 and 13;

' Some of the brushes the knots set at right angle to the surface o the brush blank, others cells in the deemed feasible.

now in vogue have have the knots set gradually inclining from the middle ofthe length of the brush blank toward its ends, and still others have the knots splayed both.' f the brush blank. As clearly shown 1n Figs. 18 and19, in its ordinary construction the full size multiple-brush machine arranged as shown and described sets the knots at right angles to vthe surface of the blank longitudinally and practically so transversely. The present invention provides means for splaying the knots from the middle of the length of the brush blank toward its ends and from the middle row toward the sides of the brush.. The complete machine-Figs. 11, .12, and 13-.-is accordingly herein shown as'it is constructed for row-splayed brushes.

For knot splayed .brushes the cells 52 the middle of lthe length of the brush blank` most of the brush their fasteners intovthe angular cells,

f Iand the toward its ends, as shown in Figs. 12and 21, and also from the middle of the width of the brush toward its sides, Figs. 13 and 20. In machines now in use the brush blank, or stock, is repeatedly rocked by hand so as to bring each individual angular cell successively in line with the tuft inserters; inv others, particularly in rowtuftinserting machines, the blank is rocked so as lto bring the entire row in line with the inserters, but only in one direction. The present invention provides for splaying the knots automatically both longitudinally and transversely of the brush without rocking the brush blank.

To direct the bights of the doubled tufts and their fasteners into angular cells bored so as to incline longitudinally of the blank, the conduits 50c may milled .at corresponding angles and individual plungers 62 held movable vertically on ably against the tension of the springs Sc, as shown in Fig. 23. To economize in the height of the machine vand in tlie expense of building the same, I "prefer to carry out this part of my invention in the manner shown in Figs; 12 and 21; inwhich the conduits 50 are formed parallel to each other and a plate 90 having holes 91, each of which is drilled at such an angle as to register with both the cell 52 and the conduit 50, is interposed between the plates 49 and the brush blank 37 containing the row of cells 52 opposite e thereto. The angular holes 91 thus communicate between the conduits 50 and the cells 52 and Vin operation direct the knots an an when the brushes are removed the knots assumethe angle of the cells. For long knot fasteners, such as wire staples, some of the conduits 50 and the holes 91 are slightly relieved at 92see enlarged view Fig. 22, so as to permit the fastener to-turn the corner; teethl 63, servingas staple drivers,

be able to enter .the angular cells and bear on the heads of the knot fasteners, as clearly shown in Figs. v12 and 21. The cells 52 arel also bored at an angle to the face of the blank 37 in respect to its width.. To effect the setting of the knots at angles diverging from the middle line' of thevwidth of the brush blank is, in av circular machine, readily accomplished by arranging `the brush..- blanks in a smaller circle.` It is, however, on as large a number of brush multaneously vas possible in order to reduce the cost of labor. As maybe seen by reference to Fig. 18, in the full-size machine the divergency of the knots seen in Fig. 13 disappearspractically entirely. To effect divergency of thelkn'ots vfrom the middle lines towardy the sides of the brush, the tuft inserters 62, andthe conduits 50 into whic are shaped so as to they plunge, ofthe .groups a and c tinvthe 'f desirable, to 4operate blanks a rod Rc prefer-y present illustration) are arranged so as to that each row is at right angles to one of course off the radial lines, as indicated by the composite knot-convey' g channels 81, the dot-and-dash lines in Fig. 13. By this 82, 83, previously mentioned, and in perfect means the knots on each side of the middle angular alinement therewith, as clearly row are set' at an angle'to the middle row. v shown in Fig. 13. By somesuitable means As knot splayedf brushes have usually preferably of the kind hereinafter described, 70 more than three rows of knots andthe rows the knot fasteners in said receptacle are of knots in such brushes are generally stagconstantly urged to move toward the wall gered, and as the paramount object of the 60X", and thus upon withdrawing the blade multiple brush machine is to construct and 62, y or the individual plungers 62X-Fig. 75 arrangeits mechanisms so as to'be able to 21,-after 4inserting a row of knots into thek produce a large number of brushes in one cells, the fasteners bearing against said incontinuous operation lasting asl little ltime sertersenter. the spaces next adjacent the as possible, I prefer to accomplish the splay-` tips ofpsaid fasteners thus vacated by the ing of the knots in such brushes transversely latter, and by this means a knot fastener 80 of the brush in the manner shown in' Fig. is automatically deposited in the path of 20.
